These things are 2 in one box kits, and called "easybuild".....hmm? I nearly destroyed the first one I built as it was such an awkward build. But I learned from the first one and manged to scrape the second one together reasonably ok. I also did the second one with a 25mm Bushmaster barrel instead of the flimsy kit plastic one. These things are tiny, and one will fit in the back of a merlin chopper.
Cheers,
Chris.
